A gear 34 is also meshed with the ring gear 2T and is housed in the housing 28h. The gear 34 is keyed on one end oi a drive shaft 35 journaled in bearings 36 and 37 on the frame 2, and a gear 38 is keyed to the opposite end of the said shaft.

The gears 33 and 38 are meshed with a single idler gear 39 journaled on a stub shaft 40 secured in the frame 2. A pinion 41 1s keyed to the end of a drive shaft 42 and ineshed with the idler gear 39. The shaft 42 extends from end to end of the machine and has a drive pinion 43 keyed to the end opposite from the pinion 41. The gears 29 and 34 engage the ring gear 27 at points a greater distance apart than the length of opening in the ring gear so that one of said gears will always be 1n driving engagement with the ring gear segment.

A spool support 44 is secured to the ring gear 27 and is provided with a spindle 45 on which is mounted a spool of tying wire 46 for wrapping and tying the bundles of wire. A wire guide 4T is also secured to the support 44.

In operation when the ring gear 27 is rotated in the casing 28 the spool ot tying wire 46 will be around the annulus of the annular bundle of wire, forming a plurality of wraps.

In order to secure or tie the wraps of tying wire, a twisting mechanism is provided for twisting the several wraps of tying wire together. The twisting mechanism comprises a vetical spindle 48 mounted in a` bearing 49 in the 'frame 2 and having a disk 50 secured to its upper end. A twister post 51 having a base 52 is secured on and adapted to rotate with the disk 50. A tapered twisting linger 53 is secured to the post 5l and adapted to project outwardly under the bundle of wire being tied, so as to lie between the bundle and the wraps of tying wire, that is, the tying wire is adapted to be wrapped around the bundle and linger 53.

The spindle 48 has a bevel gear 54 keyed to its lower end which gear is ineshed with a bevelgear 55 on a shalt, 56 which is journaled in bearings 5T on the frame 2 and projects through the end of the trame. A drive pinion 58 is keyed to the end of the shaft 56, projecting through the end of the frame 2.

When the shaft 56 is rotated the gears 54 and 55 will be rotated so as to rotate the spindle 48 and twisting linger 53, thus twisting the wraps of tying wire together. Vhen the wraps ot tying wires are twisted together by the linger 53 a tight loop is formed on the finger and in order to remove this loop as the rollers l0 are rotated to advance the bundle ot wire being tied. we. provide a kicking or stripping mechanism to kick the loop free on the tinger 53.

The kicking or stripping mechanism coinprises a stripping traine 60 slidably mounted on the iingcr 53 and having a pair ol' downwardly extending ears 6l which project; downwardly on each side ot the post 5l. A leaf spring 62 is secured at one end to the post 5l and has its other end loosely engaging a tansverse pin 63 extending between the ears 6l. so as to normally hold the stripping frame 60 in retracted position.

A rock shaft 64 extends transversely of the frame 2 and is journaled in bearings 65. An actuating arm 66 is keyed on the shaft 64 and is adapted to engage the ears 6l ot the frame 60 when the shaft 64 is rocked and thus move the frame 60 forwardly along the linger 53 to kick or strip the loop of tying wire loose on the linger.

The shaft 64 is adapted to be rocked by a lever 6T which is secured intermediate its ends on the shaftl 64 and bas a link 68 pivotally secured to one end and extending downwardly through a guide 69 secured to the traine 2. The link 68 has a roller 76 thereon adapted to be engaged by a cani 'il secured to the drive shaft 22 so that said cani will litt the roller 70 and link 68 at, the start of the shaft 22, thereby operating the stripping lframe at the start of the inaterial supporting rollers 10.

The end ot the lever 6T opposite that to which the link 68 is secured, has a plunger 72 pivotally secured thereto which is adapted to project downwardly through an opening in the frame 2 when the shaft 64 is rocked and to compress a coiled spring 73, which spring is adapted to return the shaft 64 and its accompanying mechanism to nor mal position after the high point of the cam 7l passes under roller 70.

In order to prevent the strand ot wire leading troni the spool 46 following the bundle of wire being tied when the bundle is advanced, a colnbined wire guide and depressor arni 75 is provided which is pivotally supported intermediate its ends on a bracket 76 on the casing 28 and has one end extending across the normal path ol the strand of tying wire troni the spool 4t6. The arm 75 has a wire guide slot or groove 77 through which the tying wire passes lo the bundle to be tied. 'l`he opposite end of the arin T5 is pivotally connected to a plunger T8 which has a roller Til journaled on a pin secured in its lower end. 'l`lie roller 79 is adapted to ride on a roller trank 8l on the disk 50. which track has a raised point or cam 82 thereon adapted to torre the roller 79 and plunger 78 upwardbY at each revolution ol` the disk 50.

The. operator will then tramp on the treadle 107 so as to withdraw the pin 99 and allow the clutch B to engage and start the machine. iVhen the clutch engages, the segmental gear 109 will rotate and the teeth 110 will first engage the pinion 124 and operate the train of gears 125, 126, 129 and Llb so as to rotate the shaft and operate the gears 11, 39, 33, and 3S. rl`he gears 33 and 3S are. keyed to the shafts 30 and 35, respectively, which also carry the operating gears 29 and 31 tor the segmental gear ring 27 which carries the spool of tying wire. As the gears 29 and 34C are rotated they will rotate the gear ring 27 so as to make two complete revolutions of the ring gear and consequently two complete wraps of tying wire around the annulus of the bundle of wire. It will also be noted that due to the position ot the twisting finger 525, the tying wire will also be wrapped under this finger so that when the wrapping is completed the finger 53 will be positioned between the wraps and the bundle in readiness to twist the wraps together. The gearing is so arrangedthat the number ot teeth in the drive gear segment 110 is sullieient to cause two complete revolutions ot the ring gear 27. l

After the gear 109 has moved past the pinion 124 it will next engage the pinion 1Q() and operate the gears 121 and pinion 5S, so as to rotate the shaft 5G and gears 54 and 55, thus rotating the spindle 48 and disk 50 and the twisting finger 53. The gearing 120, 121, 58, 54, and is so arranged that the teeth segment. 110 of the gear 109 will be sufficient to operate such gears to cause two complete revolutions of the twisting finger 53. As the disk 50 is rotated the eam 82 will be moved under the roller 79, thus. operating the guide and depresser arm 7 to move the strand of tying wire out of the path of the finger 53.

After the segment of teeth 110 of thel gear 109 has moved past the pinion 120 it will next engage the pinion 11G and operate the gears 117 and QG. so as to rotate the shaft 2Q. The shaft 22 will in turn drive the shaft 17 through the sprockets QO--Ql and chain Q3. and the shaft 17 will in turn rotate the shafts 11, carrying the supporting rollers 10. through the bevel gears 15 and 1S. The arrangement ot' gearing in this last named drive is such that the rollers 10 will be rotated only sufiieient to rotate the. bundle ot wire being tied a portion of a revolution so that a new point will be presented for tying.

The operation of the rollers 10 completes one cycle of the operation of the machine and the clutch sleeve or collar 9o will have revolved so that. the pin 99 has again entered the slot or groove 98 and caused the sleeve 96 to be retracted to disengaged position and stopped the drive gear 109.

The. operator will now be compelled to again tramp on the treadle 107 to start anfvther cycle and complete another tie, and a gain advance the bundle ot wire, the cycles being repeated until the desired number of ties are made around the bundle.

lVhile we have described and illustrated one specific embodiment of' our invention it will be understood that we do not wish to be limited to the specific embodiment illustrated, since various modifications may be made without departing from the scope ol' our invent-ion as defined in theappended claims.
